Before blaming your provider, try these fixes. Many "slow broadband" problems are actually WiFi issues you can solve yourself.

Step 1: Test Your Actual Speed

Before anything else, measure what you're getting:

Connect via ethernet cable (not WiFi)

Close all other apps and devices

Run speed test: speedtest.net or fast.com

Compare to your plan: Are you getting what you pay for?

Interpreting Results

| Your Plan | Expected Speed | Problem If Below | |-----------|----------------|------------------| | 100Mb | 80-100Mb | 50Mb | | 300Mb | 250-300Mb | 150Mb | | 500Mb | 400-500Mb | 250Mb | | 1Gb | 800-1000Mb | 500Mb |

Getting expected speeds on ethernet but slow on WiFi? Your problem is WiFi, not broadband. Jump to WiFi Fixes. Getting slow speeds even on ethernet? Your problem is the broadband connection. Jump to Broadband Fixes.

Fixing WiFi Problems

Problem: Slow WiFi Throughout House

Solution 1: Reposition your router

Central location in the home
Elevated (shelf height, not floor)
Away from walls if possible
Not in a cupboard or behind furniture

Solution 2: Reduce interference Keep router away from:

Microwaves
Baby monitors
Cordless phones
Other routers/access points
Large metal objects
Fish tanks (water blocks signals)

Solution 3: Change WiFi channel

Log into your router (usually 192.168.1.1)

Find WiFi settings

Try a different channel (1, 6, or 11 for 2.4GHz)

Use 5GHz for faster speeds (shorter range)

Solution 4: Update router firmware Outdated firmware causes problems:

Check router manufacturer's website

Download latest firmware

Update via router admin page

Problem: WiFi Slow in Certain Rooms

Solution 1: WiFi extender

Budget option: ~€30-50
Extends existing signal
Can reduce overall speed

Solution 2: Mesh WiFi system

Better option: ~€150-300
Creates seamless network
Consistent speeds throughout
Examples: Google Nest WiFi, Eero, TP-Link Deco

Solution 3: Powerline adapters

Uses electrical wiring
Ethernet-like reliability
~€50-80 for a pair
Works well in older homes

Solution 4: Run ethernet cable

Most reliable solution
DIY or hire electrician
Permanent fix

Problem: Too Many Devices

Modern homes have dozens of connected devices:

Smart TVs
Phones and tablets
Laptops
Smart speakers
Security cameras
Smart home devices

Solutions:

Upgrade router: WiFi 6 handles more devices better
Prioritize devices: Use QoS settings to prioritize important devices
Separate networks: Put IoT devices on 2.4GHz, keep 5GHz for important devices
Disconnect unused devices: Smart devices you don't use still consume bandwidth

Fixing Broadband Problems

Problem: Slow Speeds on Ethernet

If wired speed test shows significantly less than your plan:

Check 1: Restart equipment

Turn off router for 60 seconds
Restart any networking equipment
Simple but often effective

Check 2: Cable quality

Old/damaged ethernet cables limit speed
Use Cat 6 or better for gigabit
Replace if over 5 years old

Check 3: Time of day

Test at different times
Evening slowdowns = network congestion
Worse on older infrastructure

Check 4: Contact provider If consistently slow:

Document speed tests (date, time, results)

Call provider with evidence

Request line test

Ask about fault investigation

Problem: Intermittent Connection

Connection drops randomly:

Causes:

Faulty router
Damaged cabling
Line fault
Interference

Fixes:

Request router replacement
Ask provider to check line
Check internal wiring isn't damaged
Try wired connection (rules out WiFi)

Problem: High Latency/Ping

Speed is okay but everything feels slow:

Check your latency:

Open Command Prompt (Windows) or Terminal (Mac)
Type: `ping google.com`
Normal: under 30ms
Problematic: over 100ms

Causes:

Network congestion
Distance from exchange
Satellite/wireless connection
VPN routing

Fixes:

Switch to wired connection
Disable VPN temporarily
Contact provider if consistently high
Consider fibre upgrade if on old ADSL

When to Switch Provider

Switch if:

Speeds consistently below 50% of plan
Provider won't fix ongoing issues
Better options available in your area
Your contract has ended anyway

Before switching, check:

What's actually available at your address
Whether the issue is your WiFi (which follows you)
If fibre has recently become available

Provider-Specific Issues

Eir Slow Speeds

Common with older Eir connections:

FTTC (fibre-to-cabinet): Limited by copper—max ~100Mb
Distance from cabinet: Farther = slower
Old wiring: Internal phone wiring degrades

Fix: If Eir FTTH or SIRO is available, upgrade to true fibre.

Virgin Media Slow Speeds

Virgin is usually fast, but:

Evening congestion: Shared cable network slows at peak times
Node issues: Local network problems affect whole areas
Old modem: Request replacement if >3 years old

Fix: Report to Virgin, check for area issues, request modem upgrade.

5G/4G Slow Speeds

Wireless broadband varies by:

Signal strength: Position router near window
Congestion: Shared with mobile users
Time of day: Peak times slower

Fix: Try different router positions, check if fibre has become available.

Quick Fixes Checklist

Try these in order:

[ ] Restart router (leave off 60 seconds)
[ ] Test with ethernet cable
[ ] Move router to central location
[ ] Update router firmware
[ ] Change WiFi channel
[ ] Check for interference sources
[ ] Reduce connected devices
[ ] Run speed tests at different times
[ ] Contact provider with evidence

Summary

Most "slow broadband" is actually slow WiFi.

Quick wins:

Test via ethernet first

Reposition router

Reduce interference

Consider mesh WiFi for large homes

If broadband itself is slow:

Document speed tests

Contact provider

Check if better options are available

Switch if contract allows
